Bonjour à tous,
J'aimerai crée un objet COM, en utilisant la fonction :

Code :

CoCreateInstance(
REFCLSID rclsid, /*Class identifier (CLSID) of the object */
LPUNKNOWN pUnkOuter,
/*Pointer to whether object is or isn’t part of an aggregate */
DWORD dwClsContext,
/*Context for creating the object*/
REFIID riid,
/*Reference to the identifier of the interface (a pointer in C, a reference variable in C++*/
LPVOID * ppv
/*Indirect pointer to requested interface if successful, NULL otherwise*/);

Sauf que je ne sais pas trop quoi mettre comme paramètre.
Je sais que le CLSID est l'identifiant unique de l'objet et je l'ai trouvé dans la base de registre,mais par contre pour l'interface je ne sais pas.
j'ai fait des recherches mais ça reste un peu flou pour moi, si quelqu'un a un exemple pour m'aider.
Je vous remercie d'avance.

Je sais que le CLSID est l'identifiant unique de l'objet et je l'ai trouvé dans la base de registre,mais par contre pour l'interface je ne sais pas.

Ce n'est pas bien de fouiller dans le registre. Pour utiliser un composant COM, il faut la doc de ce composant, il ne suffit pas de connaître son id de classe et les ids de ses différentes interfaces. Sans doc, c'est perdu d'avance. Quel classe veux-tu instancier néanmoins, au cas où je pourrais t'indiquer où trouver la doc.

[fregolo52]

Petite notion de "vocabulaire" : Tu ne veux pas créer un objet COM mais l'instancier.

Avec Visual Studio, il y a un outil nommé OLEViewer.
Il permet de charger l'objet COM (dll ou exe) et de voir les prototype des interfaces.

[dev_nath]

Bonjour et merci pour vos réponses,

Melem: le but de mon travail est de faire communiquer deux logiciels via les objets COM.
Pour l'instant j'ai crée un projet sous Visual Studio et j’essaie déjà de communiquer avec un seul logiciel.
Pour les deux logiciels j'ai la doc fournie.

fregolo52 : peux-tu stp me dire ou se trouve cet outil, j'ai Visual Studio 2010, et c'est ma première utilisation donc je ne le maitrise pas bien.
Merci pour la correction du vocabulaire.

Merci pour votre aide.

[fregolo52]

je n'ai pas 2010 sous la main.
Mais sous 2005, dans le menu "Tools" tu dois y trouver Ole View.
Si tu ne l'as pas télécharge-le, c'est plus simple (que de retrouver dans le setup de Visual pour cocher la bonne option).

[dev_nath]

j'ai installé OLEView, j'ai trouvé le logiciel qui m’intéresse dans "type libraries",
j'ai trouvé le uuid qui correspond au CLSID(je pense), et plusieurs interfaces,
qui correspondent aux classes citées dans la doc du logiciels.
Mais j'ai pas trouvé les autres paramètres de la fonction CoCreateInstance().
Une idée de ou ils se trouvent?

Merci d'avance.

[Médinoc]

• pUnkOuter est nul puisque tu ne fais pas d'aggrégation
• Pour ClsCtx ça dépend de ce que supporte le composant. S'il contient une clé InprocServer32, tu peux l'instancier en CLSCTX_INPROC_SERVER
• riid et ppv vont ensemble: Tu y mets le GUID de l'interface et un pointeur vers ton pointeur (le B-A-BA de COM, quoi).

[dev_nath]

Merci Médinoc pour ta réponse,

riid et ppv vont ensemble: Tu y mets le GUID de l'interface et un pointeur vers ton pointeur (le B-A-BA de COM, quoi)

Pour le GUID de l'interface je l'ai, mais pour le pointeur vers mon pointeur je ne sais pas ce qu'il faut mettre, si tu peux m'expliquer un peu plus stp.

Voila ce que je fais:

}

Merci pour ton aide.

[Médinoc]

Tu dois avoir le fichier d'en-tête qui définit l'interface (si tu as juste une Type Library, en C, tu es dans la M*** mais tu peux plus ou moins reconstituer le fichier .idl avec OLEVIEW, puis recompiler le .idl pour obtenir un .h).

Et ensuite:

Est ce tu as un exemple stp parce que la je suis perdue

[Médinoc]

Ouvre la Type Library avec OLEVIEW, tu devrais avoir le moyen de voir un code IDL qui définit les interfaces.

Avec ça, tu peux utiliser le compilateur IDL de Visual (MIDL.EXE) pour obtenir le .h qui marche en C comme en C++.

[dev_nath]

J'ai compilé le fichier .idl pour avoir le fichier.h comme tu m'as dit, mais j'ai des erreurs si tu as une idée stp:

error MIDL2025 : syntax error : expecting an interface name or DispatchInterfaceName or CoclassName or ModuleName or LibraryName or ContractName or a type specification near "*■"
error MIDL2026 : cannot recover from earlier syntax errors; aborting compilation

Ainsi que beaucoup de warning du type: warning: null character(s) ignored

et un à la fin :warning: no newline at end of file


Merci d'avance.

[Médinoc]

Poste le fichier .idl.

[dev_nath]

Bonjour Médinoc,
je n'arrive pas à poster le fichier .idl sur le forum, il me met fichier non valide.
est ce que je peux te l'envoyer par mail?

Merci d'avance

[Médinoc]

Est-il trop grand pour le poster dans une balise [CODE]?

Ou en .txt?

[dev_nath]

Voila je l'ai compressé.(je n'avais pas vu qu'on pouvait mettre des .rar)

[Médinoc]

Je n'ai aucune erreur dans MIDL (Visual 2005), mais beaucoup de warnings.
En ajoutant l'option /h e3.h, j'ai pu créer le fichier.

Merci beaucoup, moi j'ai toujours les mêmes erreurs.

Voila j'ai regardé un peu le fichier .h, la dernière fois tu m'as dit :

riid et ppv vont ensemble: Tu y mets le GUID de l'interface et un pointeur vers ton pointeur

Mais la il y a plusieurs interfaces, comment je peux faire pour définir riid et ppv?
Sachant que je veux accéder à tous ces interfaces avec mon objet.

Merci d'avance.

Tu mets l'interface dont tu as besoin à l'instant. Quand tu as besoin d'une autre, tu fais un QueryInterface(). Et n'oublie pas que chaque interface doit être releasée avant d'être "oubliée"...

Merci beaucoup pour ton aide, je vais essayer ce que tu m'as dit et je te tiens informé.
